This unit has gotten me out of a few bad moments. It does everything it states it does. I think everyone should own one. It will forsure get you out of a dead batter jam everytime. Last year I installed this in my wife's car, and where we live it extremely cold here. She was at work it was -39°C not even a block heater can work properly in that temp. Anyways, her car wouldn't start. Everyone at her work there cars would not start. Plugged in this bad boy and 3 hours later, she was the only one who had her car started with no issues. This saved us a tow. So worth every penny. So now we plug this in all the time in the winter. We love this little unit. I know you would love it as well. Also this unit will prolong the life of your battery forsure. As led-acid battery's love to be full charged all the time. Don't believe me, looking up! They loose power in cold temps, so this unit will keep it topped up all the time. Haha, never get left out in the cold with this unit. If you thinking of not getting it. You can't say I didn't tell you so. Futher more, only get the one you have to install. It's best, you can buy a 2 way splitter for the block heater and this unit and plug it in at the same time. No fuss whats so ever. Perfect for brand new cars and all makes and models including Hybrid cars. NOTE : Not for full Electric cars vehicles. I've been an auto service technician for over 25 years. ## Features - MEET THE GENIUS2D — The all-new direct-mount onboard battery charger for an under-the-hood battery charging system and year-round battery maintenance. - DO MORE WITH GENIUS — Designed for 12-volt lead-acid (AGM, Gel, SLA, VRLA) batteries, including flooded, maintenance-free, deep-cycle, marine and RV batteries. - DIRECT MOUNT — Securely attaches near the battery using a durable snap-fit mounting bracket and installs easily into most surfaces with truss-head self-tapping screws for a hassle-free, reliable setup. - ENJOY PRECISION CHARGING — An integrated thermal sensor dynamically adjusts the charge based on ambient temperature, preventing overcharging in hot weather and undercharging in cold, ensuring optimal battery performance. - CHARGE DEAD BATTERIES — Charge batteries from as low as 1 volt, or use Force Mode to manually charge completely dead batteries down to zero volts.

But I’m 99% sure the loss of power has no effect at all. I base this on the fact that there’s no on or off button on the unit.(no settings) It only works or doesn’t work if it’s plugged in or unplugged. So my answer is their are no settings. So if you have power it works if you don’t it doesn’t. There is a cool feature it monitors it’s invioronent if it’s to hot it will not turn on. **Q: will this work for motorcycle batteries?** A: Yes; it works for my motorcycle, and the device is tiny enough to hide in a saddlebag. **Q: My battery is in the trunk,,can I connect it to the jump points under the hood instead of directly to the battery in the trunk?** A: Battery is in the trunk. That must be an European vehicle. Anyway, as long as you can securely tie the red and black eye hook of the charger to the jump points under the hood. I have two cars with battery in the trunk. What I did was one of vehicle I connect the NOCO charger 5-AMP, NOCO GENIUS GEN5X1 directly to the battery and on the other vehicle I use a portable NOCO 10-AMP, NOCO GENIUS10 charger to the jump points under the hood.

The mounting strap has two holes to install the plastic snap-on back to the metal of the vehicle inside the engine compartment using two self-tapping screws (provided). There are two lugs on the snap-on back that accommodate a velcro strap (also provided) which ties down the charger in addition to the snap-on back that is latched to the charger. A well thought out system to ensure that the charger cannot shake loose when the vehicle is moving. In my case I have attached the charger to the wall above the front passenger tire well of my Silverado truck. That way, the charging leads can easily reach the battery although the power lead is too short to go anywhere near the front grill (Maybe 2-3 ft long). My GFI socket is on the side of my garage, about 45ft away from the engine compartment but it's easy to run a 50ft outside-rated cable (SJTW 12/3) to the charger power cable under the hood. With the temperatures around 31 to 42 degrees F right now and a new battery I am able to keep the battery fully charged in a truck that sometimes sits on an outside concrete pad for 2-3 weeks at a time. I am very pleased with this product. It gives me piece of mind that I will always be able to crank my engine whatever the weather. It will also help me to prolong the battery life. I now own two NOCO chargers, both are able to condition a battery as well as charge it. My other NOCO charger is a NOCO GENIUS 10A waterproof marine charger which can be used for several different battery types and does a great job for my lawn tractor and 12v shed battery for LED lights. It can handle lithium batteries also which works for my kayak. My neighbors call me when they need help with charging because they now understand the problems caused by sulphates which NOCO battery chargers can deal with. NOCO make great products. I have no hesitation recommending them. (NOTE: I gave this 5 stars but only four lit up. The first one stayed empty). ## Frequently Bought Together - NOCO GENIUS2D, 2A Direct-Mount Onboard Car Battery Charger, 12V Automotive Charger, Battery Maintainer, Trickle Charger, Float Charger and Desulfator for Marine, ATV, Truck and Deep Cycle Batteries - NOCO GCP1 15A AC Port Plug, 125V Power Inlet Socket, and Waterproof Electrical Outlet Receptacle Box with 16-Inch Integrated Outdoor Extension Cord - NOCO GCP2 15A AC Port Plug, 125V Power Inlet Socket, and Waterproof Electrical Outlet Receptacle Box with Dual 18-Inch Integrated Outdoor Extension Cords --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/390817918-noco-genius2d-2-amp-direct-mount-onboard-charger-12v-battery](https://www.desertcart.co.za/products/390817918-noco-genius2d-2-amp-direct-mount-onboard-charger-12v-battery) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-30*
